I Make Stuff With Tools

My Lathe taking a finish pass on the shaft bore of the new alternator pulley

The alternator came with a pulley for a single V V-belt. The drive pulleys on the engine as well as the slave pulleys on the water pump are 5V belts. So..... I chucked up a 3" piece of 4140 I had lying around, turned on the lathe, and yelled at it till it made me this beautiful new pulley. As we all know CNC machines make parts for you, all you have to do is ask.
